Three children are going to buy some plants for their birthdays. They will plant them within circular paths. How could they do this?
On my calculator I divided one whole number by another whole number and got the answer 3.125 If the numbers are both under 50, what are they?
A few extra challenges set by some young NRICH members.
Demi, Hannah, Izobel, Celia, Joseph and
Michael from All Saints C of E Junior School sent us their solution
to this challenge. They said:
They also sent in a net of the cube:
Niharika from Leicester High Schools for Girls
Mathematicians might call that
'visualising'. Niharika sent in another solution which is the
reverse of the route above.
Niharika also tackled the second part of the
challenge which involved a cube with coloured squares painted on
it. Firstly, she labelled the grid:
She then went on to describe the route:
Niharika explained that she thought
carefully about the symmetry of each of the faces and how an odd or
even number of 'tips' might affect each face. Fantastic!
Will the reverse of Niharika's route work too,
do you think?
